### MP-105 Host to MP communication interrupted

The MP received what appeared to be the start of a host message over the RS-232 communication line but the message was not properly terminated and at least ten (10) seconds have elapsed since the last character was received. This may have been caused by one of the following:

- A loose RS-232 connection

- Cycling power on the host computer

- A host software failure

- An electrically noisy environment.

For more information, see "MP Error Codes".

What you should do:

1. Check and tighten both ends of the host to MP RS-232 cable.

2. To clear the error, click Clear error in the XYZ Display window.

To clear it using an RCU-II, press and hold down the Servo Power Off button and then press the Joy button twice.

3. If the error occurred while executing a measurement routine, then assume that the measurement routine operation has been seriously disrupted. Abort the measurement routine.

4. If the error reoccurs, contact your Giddings & Lewis service representative.

(Exception: See note below.)

If the error occurred shortly after turning on the host computer, then it is almost certainly the result of this since it is normal for some random character to be generated over the RS-232 line when the PC power is cycled. In this case, the error can be cleared and ignored.
